Abstract (en)
[origin: US6560152B1] A novel non-volatile memory is disclosed. The non-volatile memory includes an array of data storage cells that individually include a storage element such as a floating gate, a control gate and first and second source/drain terminals. A current source provides a current to the first source/drain terminal of the data storage element. A node is electrically connected to the second source/drain terminal of the data storage element. A bias circuit provides a bias voltage to the node. The bias voltage varies with temperature in a manner approximately inverse to the thermal variation of the threshold voltage of the data storage element. A control gate voltage circuit provides a voltage level to the control gate of the data storage cell.
